the'opposite side of the Web are theinte gral brackets F for receiving the hearings G for the difierent-ial gearing. The brackets F are provided With complementary eapsseoured thereto by studs Thus the differential gearing is supported on one side of the frame and the drive shaft on the opposite side, the latter extending through the central aperture in the Web operative relation to the gearing.

Projecting axlally from the opposite ends of the frame A are the stub shafts I on Which are pressed the hubs J of housing'K for the step-down gearing.

-.lyl-t ans tt eg the, torque f em h lshe v-t WVhat we claim as our invention is:

1. The combination of a dead axle in the form of a structural beam, a housing secured to the end of said dead axle, a gear journaled in axial alignment withsaid dead axle located within said housing, a stub shaft secured to said gear and extending outward therefrom in axial alignment with said dead axle, a live axle extending parallel to said dead axle and offset with respect to the axis of said housing, a gear on said live axle meshing with said first mentioned gear, a cover for said housing having a hollow hub through which said stub shaft passes, a wheel hub journaled upon said hollow hub, and a torque connection between said stub shaft and wheel hub.

2. The combination of a dead axle in the form of a structural beam having its greatest width at the center and tapering towards opposite ends, a stub shaft projecting from the end of said axle, a housing having a hub mounted upon said stub shaft, a cap for said housing having a hollow outwardly projecting hub, a wheel hub journaled upon said hollow hub, an internal gear wheel within said housing provided with a stub shaft projecting outward through said hollow hub, a live axle extending parallel to said dead axle and offset with respect to the axis of said housing, a gear on said live axle meshing with said internal gear, and a torque connection between the outer end of said stub shaft and said wheel hub.

3. A dead axle in the form of a structural beam having a central vertical web and top and bottom flanges, said beam diminishing in width from the center towards its ends, a stub axle integral with said beam projecting from the end thereof, a gear housing having a hub sleeved upon said stub axle, adjacentflanges upon said beam and gear housing hub connected to each other to transmit torque stresses, a cap for said gear housing having a hollow outwardly projecting hub, a wheel hub journaled upon said hollow hub, an internal gear wheel within said housing, a stub axle upon said gear wheel projecting outward from said hollow hub, and a cap secured to said stub axle and transmitting the torque stresses therefrom to said wheel hub.

4. The combination of a dead axle in the form of a structural beam having a centrally vertically extending web and flanges at the top and bottom thereof, said beam tapering'from the center towards its opposite end, integral brackets projecting later ally from said web on one side thereof for supporting the differential gearing, a housing integral with and projecting from the opposite side of said web for receiving the drive shaft, and a detachable casing for enclosing said differential gearing.

5. The combination of a dead axle in the form of a structural beam, a housing secured thereto having a hollow hub, a wheel hub journaled on said hollow hub, a stub shaftwithin said hollow hub and connected to said wheel hub, an internal gear journaled in said housing and secured to said stub shaft, a live axle offset from said dead axle and axis of said hollow hub and a gear mounted on said live axle and meshing with said internal gear.

6. The combination of a dead axle inthe.

form of a structural beam, a housing for the drive shaft projecting from one side of said dead axle, a mounting for the differential gear, projecting from the opposite side of said dead axle, said axle being centrally apertured for the operative connection of said drive shaft to said differential gearing, a housing for said differential gearing, a housing mounted at the outer end of said dead axle, a cover for said housing having a hollow outwardly projecting hub, a wheel hub journaled upon said hollow hub, an internal gear wheel within said housing provided with .a stub shaft projecting outward through said hollow hub, a torque connection between said stub shaft and said wheel hub and a driven shaft extending from said differential gearing housing to the housing at the outer end of said dead axle into operative relation to said internal gear, said driven shaft being parallel to said dead axle and the axis of said hollow hub.

7 The combination of a dead axle in the form of a structural beam having a central vertically extending web provided with an aperture, said beam tapering from the center towards its opposite ends and having flanges at the'top and bottom thereof, integral brackets projecting laterally from said web on one side thereof, an integral housing projecting from the opposite side of said web, a differential gear having bearings directly mounted in said integral brackets, a casing for enclosing said differential gear detachably mounted on said dead axle inde-- HOMER E.
